How to Reduce Noise of Worm Gear and Worm Reducer

As everyone in the reducer industry knows, the noise of the reducer, especially the worm gear reducer, is a headache for many reducer manufacturers.



Reducing noise and ensuring non-chaotic operation is the first prerequisite for the quality of reducer. For how to achieve this goal, many scholars at home and abroad regard the change of meshing stiffness of gear teeth as the main factors of dynamic load, vibration and noise of gears.



The method of modification is used to minimize the fluctuation of dynamic load and velocity in order to reduce noise. This method has been proved to be effective in practice.

However, in this way, the process needs to be modified. After years of research, a gear design method is proposed to minimize the meshing impact speed by optimizing gear parameters, such as displacement coefficient, tooth height coefficient, pressure angle and central distance. The ratio of meshing impact speed to meshing impact speed is in a certain range. The gear design method can reduce or avoid meshing pitch impact, and can also significantly reduce the gear noise of worm and worm reducer.
